Familial pancreatic cancer is a relatively rare but serious disease that is associated with a high mortality rate. It is characterized by malignant growth of pancreatic cells, which can lead to dysfunction and various complications. The disease can be hereditary and is more common in people with a family history of pancreatic cancer. Pancreatic cancer is often diagnosed at a late stage due to the lack of specific symptoms in the early stages of its development, which makes it especially dangerous for the patient's health.
History of the disease and interesting historical facts
The history of pancreatic cancer research spans many decades. The first mentions of diseases associated with the pancreas date back to ancient civilizations. However, the scientific basis and diagnosis of pancreatic cancer began to develop only in the late 19th century, when the first studies related to the anatomy and function of this organ were conducted. In the 1920s, the connection between heredity and the development of the disease became known; at that time, the term “familial cancer” was formulated. In recent decades, significant strides have been made in understanding the molecular mechanisms underlying this disease, which has contributed to earlier diagnosis and new treatment methods.
Epidemiology
According to epidemiological data, pancreatic cancer is one of the leading oncological diseases, starting from the fifth place in mortality in most developed countries. In Russia, about 20,000 new cases are registered annually. According to the World Health Organization, the incidence increases in the age group over 65 years. It is important to note that the incidence is significantly higher among smokers and people with diabetes. According to research, people aged 55 to 64 years have about twice the risk of developing pancreatic cancer than younger people.
Genetic predisposition to this disease
To date, it has been established that certain genes and mutations play a significant role in the development of familial pancreatic cancer. The most studied of these include BRCA2, PALB2, and CDKN2A. The BRCA2 and PALB2 genes are associated with hereditary cancers, including breast, ovarian, and pancreatic cancer. Patients with mutations in these genes have a significantly increased risk of developing the disease. Research suggests that having a family history of pancreatic cancer may be associated with multifactorial hereditary markers, although many of these remain to be studied.
Risk factors for the development of this disease
Various factors may contribute to the development of pancreatic cancer. These include:
- Smoking: People who smoke have a significantly higher risk of developing the disease than non-smokers.
- Diabetes: There is a statistically established association between diabetes and an increased risk of pancreatic cancer.
- Obesity: Excess body weight is an additional risk factor associated with metabolic disorders.
- Family history: Having a history of cancer in your family increases your risk of developing the disease.
- Chronic pancreatitis: Long-term inflammation of the pancreas also increases the likelihood of malignant degeneration of cells.
- Diet: Diet rich in processed foods and lacking in fruits and vegetables.
Diagnosis of this disease
Diagnosis of pancreatic cancer is a complex process that involves several stages. The main symptoms that may indicate the disease include:
- Pain in the upper abdomen.
- Loss of appetite and unexplained weight loss.
- Jaundice.
- Changes in stool.
- Hyperglycemia.
Laboratory tests may include levels of cancer markers such as CA 19-9. Radiological tests, including ultrasound, CT, and MRI, can visualize the tumor and assess its spread. Other diagnostic methods may include endoscopic ultrasonography with biopsy. The differential diagnosis should exclude other diseases such as chronic pancreatitis or gallstones.
Treatment
Treatment for pancreatic cancer can vary depending on the stage of the disease and the patient's overall health. General treatment may include:
- Surgery: tumor resection is the only potentially curative treatment.
- Chemotherapy: Usually given after surgery and may be used as neoadjuvant or adjuvant therapy.
- Palliative care: focuses on improving quality of life and reducing symptoms in advanced stages.
- Targeted and immunotherapy: targeting molecular mechanisms of the tumor.
List of medications used to treat this disease
Medicines used to treat pancreatic cancer include:
- Folfirox (5-fluorouracil, leucovorin, oxaliplatin)
- Gemcitabine
- Capecitabine
- Naparib
- Sorofenib
Disease monitoring
Monitoring of patients with pancreatic cancer involves regular examinations to monitor disease progression and assess the effectiveness of treatment. The prognosis of the disease depends on the stage at diagnosis and the patient's overall health. Major complications may include metastasis, ascites, and indigestion. The prognosis is generally poor, especially in the later stages.
Age-related features of the disease
The dynamics of pancreatic cancer incidence varies depending on age. In people over 65, it occurs significantly more often than in young people. In the age group under 50, the disease is rare, but, as a rule, manifests itself in a severe form.
Questions and Answers
- What are the main symptoms of pancreatic cancer? The main symptoms include abdominal pain, weight loss, jaundice and changes in stool.

Advice from Dr. Oleg Korzhikov
It is important to remember that regular medical examinations can help in early diagnosis of the disease. Questions that often arise in patients should be heard and discussed with the doctor. If you suspect pancreatic cancer, do not delay a visit to a specialist. Remember the importance of health and contact a doctor at the first signs of illness. Your family and your loved ones will be the first support in the fight against this disease.
